 - Review implementations and coordinate bug fixes via Tier 4 QA.
 - **CRITICAL: ATOMIC PER-TASK COMMITS**: You MUST commit your progress on a per-task basis. Immediately after a task is verified successfully, you must stage the changes, commit them, attach the git note summary, and update `plan.md` before moving to the next task. Do NOT batch multiple tasks into a single commit.
+- **Meta-Level Sanity Check**: After completing a track (or upon explicit request), perform a codebase sanity check. Run `uv run ruff check .` and `uv run mypy --explicit-package-bases .` to ensure Tier 3 Workers haven't degraded static analysis constraints. Identify broken simulation tests and append them to a tech debt track or fix them immediately.

 **Context:** Running `uv run ruff check .` and `uv run mypy --explicit-package-bases .` revealed massive technical debt in type safety (512+ Mypy errors across 64 files, 200+ remaining Ruff violations). The `gui_2.py` and `api_hook_client.py` files specifically have severe "Any" bleeding and incorrect unions.
 **Goal:** Resolve all static analysis errors. Enforce strict `mypy` compliance, remove implicit `Optional` types, and fix ambiguous variables (`l`). Integrate `ruff` and `mypy` into a CI pre-commit hook so Tier 3 workers are forced to write type-safe code going forward.
 
+### `test_suite_performance_and_flakiness`
+**Context:** Running `uv run pytest` takes over 5.0 minutes to execute and frequently hangs on integration tests (e.g. `test_spawn_interception.py`). Several simulation tests (`test_sim_ai_settings.py`, `test_extended_sims.py`) are also currently failing or timing out. 
+**Goal:** Audit the test suite for `time.sleep()` abuse. Replace hardcoded sleeps with `threading.Event()` hooks or robust polling. Isolate slow integration tests with `@pytest.mark.slow` and ensure the core unit test suite runs in under 10 seconds to maintain high-velocity TDD.
